  1. Forget Code
  2. C#
  3. Writing into a file using WriteAllText()
We can use File.WriteAllText(Filepath) for writing the content to a file.
Remember, the previous content will be no more and the new content will be written by the File.WriteAllText().

  1. using System;
  2. using System.IO;
  3.  
  4. namespace forgetCode
  5. {
  6.     class Program
  7.     {
  8.         static void Main(string[] args)
  9.         {
  10.             string path = "D:\\test.txt";
  11.             if (File.Exists(path))
  12.             {
  13.                 Console.WriteLine("Please enter new content for the file:");
  14.                 string newContent = Console.ReadLine();
  15.                 File.WriteAllText(path, newContent);
  16.             }
  17.  
  18.           
  19.         }
  20.     }
  21. }
  22.  


Output:
The content will be written newly (Deleting previous content) to the mentioned path.
